RHSA-2012:0465 - Critical: samba security update
Synopsis
Critical: samba security update
Type/Severity
Security Advisory Critical
Topic
Updated samba packages that fix one security issue are now available for Red Hat Enterprise Linux 5 and 6; Red Hat Enterprise Linux 5.3 Long Life; and Red Hat Enterprise Linux 5.6, 6.0 and 6.1 Extended Update Support.
The Red Hat Security Response Team has rated this update as having critical security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.
Description
Samba is an open-source implementation of the Server Message Block (SMB) or Common Internet File System (CIFS) protocol, which allows PC-compatible machines to share files, printers, and other information.
A flaw in the Samba suite's Perl-based DCE/RPC IDL (PIDL) compiler, used to generate code to handle RPC calls, resulted in multiple buffer overflows in Samba. A remote, unauthenticated attacker could send a specially-crafted RPC request that would cause the Samba daemon (smbd) to crash or, possibly, execute arbitrary code with the privileges of the root user. (CVE-2012-1182)
Users of Samba are advised to upgrade to these updated packages, which contain a backported patch to resolve this issue. After installing this update, the smb service will be restarted automatically.
Solution
Before applying this update, make sure all previously-released errata relevant to your system have been applied.
